OEM Charger For Asus 19v 3.42a 5.5*2.5mm

• Linear power supply: the alternating current through the transformer transformer voltage, rectifier circuit rectifier filter to get the unstable dc voltage, to achieve high precision dc voltage, must be through the voltage feedback circuit to adjust the output voltage. Advantages: this power supply technology is mature, the circuit is simple, and there is no switch power has the interference and noise. Disadvantages: the voltage feedback circuit is working in a linear state, the power consumption of the adjustment tube is large, the conversion efficiency is low, because the use of inductance transformer equipment weight.

• Switching power supply: the use of modern electronic technology, control the switch on and off time ratio, maintain a stable output voltage of a power supply, switching power supply is generally pulse width modulation (PWM) control IC and MOSFET composition advantages: high efficiency, small size, can work in a wide range of voltage. Disadvantages: the power supply circuit interference is large, failure occurs when the maintenance is difficult. In fact, it is not difficult to distinguish them according to their advantages and disadvantages. Mainly to see the volume, weight, output voltage range. The power adaptor, is to use the chip IC scheme, the product quality according to the national standard production, the voltage is completely according to customer requirements, the power is only done between 0.3w-120w
